SLIVER CAN.

Application filed. May 4,

To all whom it may concern Be it known that I, HERBERT SMITH, a citizenof the United States of America, residing at Putnam, in the county ofWindham and State of Connecticut, have invented a certain new and usefulImprovement 1n Sliver Cans, of which the following is a full, clear, andexact description.

This invention relates to cans for receiving sliver of carding anddrawing machines in cotton mills, and the like.

According to common practice, the sliver of carding and drawing machinesis delivered into cans, which are held in an upright position and arerevolved, by mechanism, under the coiling apparatus. Such coilingapparatus consists of discs, each being of substantially the samediameter as the can located there-below, said discs having an aperturenear the edge through which the sliver is discharged into the can. Thediscs are located about three inches above the tops of the cans and arerevolved in circular frames at a different speed from the speed ofrevolution of the cans. The sliver is coiled as it is discharged intothe cans and continues to build up therein until the cans are filled,thereafter the. sliver piling up until the space between the tops of thecans and coilers is filled, the sliver then exerting an upward pressureagainst the coilers which raises the latter, thereby completing anelectrical circuit which results in the .stopping of the can and coilerrotating mechanism.

The piling of the sliver between the tops of the cans and the coilerscauses the sliver to be compressed, and when the cans are moved from themachine the sliver expands greatly, so that it often falls to the floorand becomes soiled and unfit for further treatment in the next process.Sometimes, to avoid the overflow of the sliver from the can due to theexpansion of the sliver, the operator on taking the can from the machinecarefully removes the surplus sliver which projects above the top of thecan, and deposits it in another can, which requires considerable time.

The object of this invention is to eliminate the waste of sliver and theconsequent spoiling thereof by reason of the oveflowing of the sliverfrom the cans as they are removed from the machine, and with this objectin view an important feature of the invention consists in an extensiblemember 1923.

which is applied to the sliver can, and is free to move telescopicallytherein. Such extension is normally withdrawn within the upper portionof the can, but is adapted to extend upwardly from the can as the sliverexpands when the can is removed from the machine, the rising of theextension with the expanding sliver serving to retain the sliver andprevent its falling from the can, or from becoming soiled or dama ed byreason of its extension beyond the protecting wall of the can.

The invention will be best understood from the following description,when considered in connection with the accompanying drawings, in which:

Fig. 1 is a plan view of the invention;

Fig. 2 shows the automatic extension in side elevation;

Fig. 3 is a longitudinal section, on the line 83 Fig. 1;

Fig. at is a section on the line 44, Fig. 2, viewed in the direction ofthe arrows;

Fig. 5 is a plan View of a sliver can with the extension thereon, and,

Fig. 6 is a section on the line 66, Fig. 5.

The numeral 3 indicates a sliver can, the body portion of which isordinarily made of compressed fiber, although it might be made of anyother suitable material, said can having a bottom 5. Telescopicallyreceived within the upper open end of the can is a cylindrical section 7which is provlded at its upper edge with a rolled portion of bead 8, andalso is provided at suitable intervals around its circumference withelongated hand holes 9, herein shown as three in numher. The extension 7is slightly smaller in. outside diameter than the inside diameter of thecan 3 whereby it is free to slide longitudinally in the latter.

When the parts are assembled for use the extension 7 is withdrawn withinthe can 3 and is sustained upon the upper edge of the latter by the bead8. As the sliver piles up in the can while being discharged by thecoiler it eventually rises until it fills the space between the top ofthe can and the coiler, and the sliver is then compressed and compacted,until the pressure is sufficient to effect, by a movement upward of thecoiler, the automatic stopping of the machine. The can is then removedfrom the machine, thus releasing the pressure on the sliver, whichlatter now expands and in so doing rises, carrying with it thetelescopicsection r which "follows the sliverin its upper movement andprevents it from overflowing the can and falling out upon the floor, orfrom being exposed to the danger of soiling and thus spoiling it foruse.

The hand holes 9 permit the operator to reach through the extension 7and grasp the can 3 whereby the latter may be easily handled.

The right is reserved to make such changes and variations in theconfiguration, or structural details of the parts herein shown as arecontemplated by the invention, as expressed in the following claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is:

1. A sliver can having a free and unobstructed inner surface throughout,in combination with an extensible member telescopically fitting said canand always free to automatically rise as the sliver expands, and toprevent the sliver from overflowing the can.

2. The combination with a sliver can, of a cylindrical, telescopicmember freely movable within the open end of the can, and adapted torise as the sliver expands and prevent the overfiowing of said sliverfrom the can, said extension having at its upper end means to limit itsmovement within the can.

3. The combination with a sliver can, of a telescopic extension freely vmovable within said can and constructed and arranged to automaticallyrise within the can, so as to increase the capacity of the can, underthe expansive force of the sliver when the latter isreleased saidextension being provided with an outwardly rolled upper edge which formsa stop to limit its movement into the can. v

4. The combination of a silver can, of a telescopic extension freelyfitting the open end of the can and adapted to rise automatically as thesliver expands, said extension being provided with a hand hole to enablethe'operator to reach through the extension and grasp the can.

In testimony whereof I have hereunto set my hand this th day of April A.D. 1.923.
